Marine Mammals As Sentinel Species for Oceans and Human Health
Wildlife and Marine Animals Veterinary Pathology 48(3) 676-690 ª The American College of Marine Mammals as Sentinel Species for Veterinary Pathologists 2011 Reprints and permission: Oceans and Human Health sagepub.com/journalsPermissions.nav DOI: 10.1177/0300985810388525 http://vet.sagepub.com G. D. Bossart1 Abstract The long-term consequences of climate change and potential environmental degradation are likely to include aspects of disease emergence in marine plants and animals. In turn, these emerging diseases may have epizootic potential, zoonotic implications, and a complex pathogenesis involving other cofactors such as anthropogenic contaminant burden, genetics, and immunologic dysfunc- tion. The concept of marine sentinel organisms provides one approach to evaluating aquatic ecosystem health. Such sentinels are barometers for current or potential negative impacts on individual- and population-level animal health. In turn, using marine sen- tinels permits better characterization and management of impacts that ultimately affect animal and human health associated with the oceans. Marine mammals are prime sentinel species because many species have long life spans, are long-term coastal residents, feed at a high trophic level, and have unique fat stores that can serve as depots for anthropogenic toxins. Marine mammals may be exposed to environmental stressors such as chemical pollutants, harmful algal biotoxins, and emerging or resurging pathogens. Since many marine mammal species share the coastal environment with humans and consume the same food, they also may serve as effective sentinels for public health problems. Finally, marine mammals are charismatic megafauna that typically stimulate an exaggerated human behavioral response and are thus more likely to be observed. -

Great Blue Heron: a Sentinel Species for the State of the St. Lawrence
BIOLOGICAL RESOURCES WATER SEDIMENTS SHORELINES USES 3rd edition Great Blue Heron: A Sentinel Species for the State of the St. Lawrence The Great Blue Heron was selected as a sentinel Indicator: Contamination species, or bioindicator, of the state of the St. of the Great Blue Heron Lawrence because it occurs in both marine by toxic substances and freshwater environments, occupies a State: moderate-good position at the top of the food chain, and has a relatively limited foraging range. Contaminant concentrations in Great Blue Heron eggs indicate local contamination of the ecosystem Background they are breeding in. At high concentrations, a number of contaminants are extremely toxic There are many different factors that can impact and can cause mortality. At the concentrations bird populations, from climatic conditions to typically observed in the environment, these human disturbance.

The Dog As a Sentinel Species for Environmental Effects on Human Fertility
159 6 REPRODUCTIONREVIEW The dog as a sentinel species for environmental effects on human fertility Rebecca Nicole Sumner1,*, Imogen Thea Harris1,*, Morne Van der Mescht2, Andrew Byers2, Gary Crane William England2 and Richard Graham Lea2 1Hartpury Equine, Hartpury University and Hartpury College, Gloucestershire, UK and 2School of Veterinary Medicine and Science, The University of Nottingham, Leicestershire, UK Correspondence should be addressed to R N Sumner; Email: [email protected] *(R N Sumner and I T Harris contributed equally to this work) Abstract Despite the vast body of evidence that environmental toxicants adversely affect reproductive development and function across species, demonstrating true cause and effect in the human remains a challenge. Human meta-analytical data, showing a temporal decline in male sperm quality, are paralleled by a single laboratory study showing a similar 26-year decline in the dog, which shares the same environment. These data are indicative of a common cause. Environmental chemicals (ECs) detected in reproductive tissues and fluids induce similar, short term, adverse effects on human and dog sperm. Both pre- and post-natal stages of early life development are sensitive to chemical exposures and such changes could potentially cause long term effects in the adult. The environmental ‘pollutome’ (mixtures of ECs) is determined by industrialisation, atmospheric deposition and bioaccumulation and characterises real-life exposure. In Arctic ecosystems, dietary and non-dietary chemical contaminants are detectable in biological tissues and linked with adverse health effects in both dogs and their handlers. In the female, such exposure could contribute to disorders such as ovarian insufficiency, dysregulated follicle development, ovarian cancer, and polycystic ovarian syndrome. -

This close association can lead to competition for resources and space, physical confrontation and transmission of disease. When the potential hazard posed by another vertebrate species exceeds an acceptable threshold, some manner of abatement or control of that species becomes necessary. Generally, integrated programs combining avoidance, exclusion, deterrence, habitat modification, reduction and removal are the most effective. The following presentation is intended to provide individuals seeking certification in Category D, The Vertebrates of Public Health Importance in California, the fundamental understanding of the biology and ecology of many vertebrate species of concern and the ethics by which they should be managed. 4 Chapter 1 5 Rattlesnakes • Class Reptilia • Family Viperidae (vipers) Taxonomy • Rattlesnakes are easily identified by their noticeably triangular head, a heat-sensing (infrared) loreal pit organ Anatomy located between the eyes and nostrils, keeled scales, vertical pupils and their namesake rattles.
